The intestinal microbiota has a significant impact on the host′s health.Dysbiosis of the gut microbiota may be associated with not only gastrointestinal disorders,but also cardiovascular diseases,such as hypertension.An increasing number of both human and animal models studies suggest that probiotics or fermented products may regulate microbial ecology of the gut and attenuate high blood pressure.The potential mechanisms include producing antihypertensive substances such as peptides,improving vascular oxidative and inflammatory level,the function of short chain fatty acids,as well as the interactions of intestinal flora and nervous system.Further exploration of the relationship between gut microbiota and hypertension offers a novel nutritional therapeutic strategy for hypertension.
